queryStringToObject

Generates an object from the given query string or URL.

• Use String.prototype.split() to get the params from the given url.
• Use new URLSearchParams() to create an appropriate object and convert it to an array of key-value pairs using the spread operator (...).
• Use Array.prototype.reduce() to convert the array of key-value pairs into an object.

const queryStringToObject = url =>
  [...new URLSearchParams(url.split('?')[1])].reduce(
    (a, [k, v]) => ((a[k] = v), a),
    {}
  );

queryStringToObject('https://google.com?page=1&count=10');
// {page: '1', count: '10'}
